Hi, I am using GCM in combination with Google AppEngine. Our service sends more then 10.000 messages every day through GCM. Almost every message is successfully delivered to the receiver.
But about every day there are one or more messages which could not be delivered according to the following stack trace: Uncaught exception from servlet java.io.IOException: Could not fetch URL: https://android.googleapis.com/gcm/send at com.google.appengine.api.urlfetch.URLFetchServiceImpl.convertApplicationException(URLFetchServiceImpl.java:137) at com.google.appengine.api.urlfetch.URLFetchServiceImpl.fetch(URLFetchServiceImpl.java:43) at com.google.apphosting.utils.security.urlfetch.URLFetchServiceStreamHandler$Connection.fetchResponse(URLFetchServiceStreamHandler.java:417) at com.google.apphosting.utils.security.urlfetch.URLFetchServiceStreamHandler$Connection.getInputStream(URLFetchServiceStreamHandler.java:296) at com.google.apphosting.utils.security.urlfetch.URLFetchServiceStreamHandler$Connection.getResponseCode(URLFetchServiceStreamHandler.java:149) at com.google.android.gcm.server.Sender.sendNoRetry(Sender.java:362) at com.google.android.gcm.server.Sender.send(Sender.java:261) at de.alamos.firemergency.apager.gcm.ApagerServlet.sendDataToAndroid(ApagerServlet.java:282) at de.alamos.firemergency.apager.gcm.ApagerServlet.doPost(ApagerServlet.java:162) ... The exception occurs at following position: MulticastResult results = sender.send(message, tokens, 5); Does anyone has some ideas what the resason of this problem could be? Thanks for your help and greetings from Germany! Simon -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
